<h1 id="NAME">NAME</h1>

<p>OSSL_SELF_TEST_set_callback, OSSL_SELF_TEST_get_callback - specify a callback for processing self tests</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/self_test.h&gt;

 void OSSL_SELF_TEST_set_callback(OSSL_LIB_CTX *ctx, OSSL_CALLBACK *cb, void *cbarg);
 void OSSL_SELF_TEST_get_callback(OSSL_LIB_CTX *ctx, OSSL_CALLBACK **cb, void **cbarg);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>Set or gets the optional application callback (and the callback argument) that is called during self testing. The application callback <b>OSSL_CALLBACK</b> is associated with a <b>OSSL_LIB_CTX</b>. The application callback function receives information about a running self test, and may return a result to the calling self test. See <a href="../man7/openssl-core.h.html">openssl-core.h(7)</a> for further information on the callback.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>OSSL_SELF_TEST_get_callback() returns the callback and callback argument that has been set via OSSL_SELF_TEST_set_callback() for the given library context <i>ctx</i>. These returned parameters will be NULL if OSSL_SELF_TEST_set_callback() has not been called.</p>
